Good stuff. interesting to see that good group with the Chinese surplus. With a Molot PU I get 1.5" 5 shots groups regularly at 100yds with the Chinese stuff, frequently 3 shots grouping under an inch. Much better than I get with other makes of surplus 7.62x54R.I have not shot much With the warm in my SVTs though Contrary to everything I hear/read, detail disassembly/reassembly of SVT is a real pain for my old arthritic hands.With the warm weather I'll try and contribute some to your study.With the way the SVT writhes in your hands when fired , I have my doubts about ever getting great accuracy with these rifles.
